mmhh. it seems less easy that i believed. yes, you can grub your ntfs partition maybe even using tc (i think, since it has the grub 0.97 version which should do that); you will find more info in the installation rubric of the site at point 6.
but... i am not sure that you can load the bzImage and tinycore.gz from your ntfs partition once grub works.
So, in order to test this before grubing your partition, you might use an empty vfat formated usb stick and syslinux it with tc in order to boot from it (you don't need to have anything on the usb stick):
syslinux -f /dev/yourusbstick
Then, create a folder named boot on your ntfs partition at the root of your master hd and copy the bzImage and the tinycore.gz into it.
Now, edit the syslinux configuration file on your usb stick with these lines:
label tinycore
kernel /boot/bzImage
append initrd=/boot/tynicore.gz quiet
Shut down your machine, plug the usb stick, start your machine and press F8 (it can be another key depending on the machine) in order to get the boot options; choose the boot from your usb stick (you can also edit this in your bios). If nothing appens, you are good to partition your hd in order to setup a linux partition, or to boot tc from an external media.
